Thomas Ridgley on the Trinity

For Ridgley, economic relations between the Trinitarian persons, as in the Covenant of Redemption, are not necessary to establish the eternal divine relations, but economic relations are sufficient to discriminate these relations. They identify the parties as three distinct, divine persons. The Father sends the Son who becomes incarnate as the Mediator, and the Spirit undertakes the task of applying what the Son has achieved to those chosen in Christ before the world was. But these relations so displayed are not are eternal, ontological distinctions of the Trinity in se. What these economic relations show and even entail, are the operations ad extra of a tri-personal God. From the economic language regarding Sonship we can infer that there is an eternal Logos who in his economic role is also human through the overshadowing and power of the Holy Spirit.
